Which acronym expansion matches Domain Name System?

• A. Domain Name System
• B. Digital Name Service
• C. Data Network System
• D. Domain Numeric System

Answer: (A)

The acronym expansion matching Domain Name System is Domain Name System. This name reflects its purpose: it’s the system that translates human-friendly domain names (like example.com) into machine-friendly IP addresses that computers use to locate services on a network. Without DNS, users would have to remember numeric IPs for every site, which isn’t practical. DNS is a hierarchical, distributed database that helps route traffic by resolving names to addresses, guiding your device to the correct server. The other options don’t match the standard expansion, since they describe different, non-existent naming conventions rather than the actual Domain Name System.
